President Donald Trump’s pick to lead the FBI billed taxpayers $2.1 million for expenses while he worked as New Jersey Gov. Chris Christie’s personal attorney, according to documents reviewed by WNYC. Christopher Wray regularly expensed meals and more than $14,000 in airfare, in addition to his hourly rate of $340 for legal services. Wray continued to bill taxpayers for personal expenses until at least one month after the trial of Christie’s underlings concluded. Among Wray’s post-trial expenses was a plane ticket priced at nearly $2,000. It is unclear what legal services Wray was providing for Christie, as the governor was not indicted in Bridgegate. The governor’s office was represented by a different attorney.
